Cable Company Sold to Canadian Group

Cogeco Cable Inc., a Montreal-based cable-television company, agreed to buy Atlantic Broadband for $1.36 billion, letting it expand into the US after a failed attempt to gain a foothold in Europe. Cogeco is purchasing the company from private-equity firms Abry Partners and Oak Hill Capital Partners in a deal that’s expected to be completed by year-end, the Canadian company said today in a statement. Quincy-based Atlantic Broadband operates cable systems in Pennsylvania, Florida, Maryland, Delaware, and South Carolina.
